Title: Relative velocity measuring device - has generator for AC magnetic field projecting into fluid stream
Inventor: LEWIS ROHN R
IPC: G01P5/08
Filed: 1974-04-24
Abstract: It comprises a generator for an A.C.magnetic field rotating about a shaft and projecting into the fluid stream. A measuring device in the A.C. magnetic field and in contact with the fluid, measures potential changes caused by the fluid flow, and delivers a corresponding A.C. signal. A sensor responding to the magnetic field, delivers a logging signal to a logic circuit, to which the A.C. signal is also applied, and which delivers a signal corresponding to the relative velocity. The magnetic generator consists of a permanent magnet unit with a set of alternating poles at one end, rotated about an axis perpendicular to the flow. The measuring device is frequency selective, and the logic circuit has a converter synchronised by the logging signal, which converts the A.C. signal into a D.C. signal.

Title: Endotracheal respiration system with minimum dead space - having separate inhalation and exhalation lines and separate gas line
Inventor: PFEIFFER ULRICH JOACHIM
IPC: A61M16/04
Filed: 1975-08-07
Abstract: The endotracheal respiration system minimises unused capacity in the lung; by having exhalation and inhalation lines which are separate in the endotracheal tube right up until they discharge into the trachea. Pref. a gas flow in a third line compensates for effective tube resistance from spontaneous exhalation. A connected circulatory system supplies fresh gas into the inhalation tube between the tube and the valve. The gas flow in the third line also builds up a pressure wave directly in front of the lungs during inhalation, so that combined with the exhalation resistance compensation the lungs can be more rapidly emptied. The system is especially designed for babies and small children.
